Unlike most vises that have a fixed center nut, all Tradesman round channel vises use a nut anchored at the rear which provides straight line pull and even pressure resulting in greater durability. The round channel design also allows for a completely enclosed spindle and nut assembly keeping debris out and lubrication in for a lifetime of smooth operation. For ultimate versatility, all Tradesman vises are equipped with main jaws, pipe jaws and a machined anvil work surface. The Tradesman XC models also include electroless nickel coating of key components, prolonging life in corrosive environments, saving hundreds of dollars on repairs and avoiding countless hours of lost work downtime.
